'For five-and-a-half or six months, she was prepping at a level... it was like she was Rocky going to go fight the Russian, Ian Drago."

Rodriquez also added: "She was lean, she was mean, and she would start her job at two-o-clock in the afternoon, her dances, and would come home around three or four in the morning. With bruises everywhere. It was just remarkable. I was so nervous for her," he recalled.

A-Rod also praised J.Lo for her dedication and mentioned that her fiance has spent six months preparing for her six-minute performance.
